The Turn of the Screw: James Henry (ALMA Classics; Evergreens)

An unnamed young governess is sent to a country house to take charge of two orphans, Miles and Flora. Yet she is soon oppressed by a sense of foreboding and deep disquiet, becoming convinced that something dark is threatening her young charges. But are supernatural forces at work, or is the danger something altogether more earthly?

Henry James's masterpiece, and widely considered to be the greatest ghost story ever written, The Turn of the Screw remains the apogee of suspenseful, haunting writing in the English language.
